I decided to remove Windows Live Messanger from my system (as I have skype also installed and active) so I

1) Un-installed Windows Live Essentials (as there is no option on Windows 7 to remove a single component)
2) Re-installed Windows Live Essentials, but only with Windows Live Mail selected

I now have no ESET 6 Windows Live Mail integration, even de-selecting/reselecting in Advanced Setup does not seem to re-enable this

The integration all worked before I removed Windows Live essentials. so I suspect a DLL/Registry key has been lost, and ESET need to make sure that when you disable/re-enable integration these are put back.

I have ESET Smart Security 6.0.115.0, and Windows Live Essentials 2012

1) Used "REPAIR" option of uninstaller (via control panel) ... this left PC with no functional A/V, Firewall and not in a well state
2) Used ESET Uninstaller in safe mode to remove Smart Security
3) Reinstalled V6 beta

Integration with Windows Live Mail is still missing

I have even
a) Removed V6 using control panel and Uninstal tool
b) Removed Windows Live Essentials
c) Run registry cleaners to make sure registry is clear and free of errors
d) Reinstalled Windows Live Mail
e) Reinstalled Smart Security V6 beta
f) Run registry cleaners to check registry is OK

even after this, the integration seems missing

Perhaps the code detects Windows Messanger in some way and thus is not active because I no longer have it installed
